MEANS FOR LABELING RADIOGRAPHS.

inseam Application filed May 8, 1915.

. To all whom it may concern:

Be it known that I, AURELIUs DE YOANNA, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedMeans for Labeling Radiographs, of which the following is a full, clear,and exact description.

This invention relates to a means for labeling X-ray photographs,commonly known as radiographs, and has for an object the production of alabel forming part of the picture.

Another object in view is to provide'a label for a radiograph whichforms part of the picture and which may contain any desired informationand may be arranged so as to appear on any part of the negative.

In the accompanying drawings: Figure 1 is a plan view of a negativeshowing a picture and a label produced from the practice of the presentinvention; Fig. 2 is a plan view of a blank label; Fig. 3 is a plan viewof the label just previous to its application to the object to bephotographed.

In labeling radiographs heretofore lettering was produced on thenegative by arranging lead letters adjacent the object to bephotographed and then the letters and the object were photographedsimultaneously. If these letters became displaced or moved out ofalinement the resulting information would be more or less confused.Also, by this method only a very limited amount of information could beproduced on the same negative as the picture.

In carrying out the present method of labeling the label is applieddirectly to the hand or other object being photographed by any suitablemeans, as for instance glue or other adhesive. The label is adapted toreceive a comparatively large amount of information and when thenegative is finally complete the label will appear in a clear formwithout injuring the image of the hand or other objectbeing'photographed.

In order that the method may be more clearly understood, reference ishad to the accompanying drawings wherein it will be observed that 1indicates the photographic plate or negative which has arranged thereona radiograph of a hand 2. Across the hand 2 appears the label 3 which ismore or less transparent and which contains a legend or information lpresenting a dif- Specification of Letters Patent.

ferent transparency. This is produced by providing a label blankb of avery thin sheet of lead commonly known as tinfoil. On this sheet of leadis provided the legend 4, as shown in Fig. 3. The legend is prepared byusing an ordinary lead pencil, a stylus or any suitable instrument whichwill cause the label 5 to be thinner at the part where the legend 4 islocated. By forming the letters or other legend on the blank eitherthinner or thicker, a desirable result will be accomplished, namely, theresulting image on the negative will be lighter or heavier, as the casemay be. In the illustration shown in the drawing a stylus having a flatnose was used and the tinfoil was merely pressed at the places where theletters appear and thereby thinned to a certain extent, thus allowingthe rays of light to penetrate with greater ease than through the bodyof tinfoil. It will be observed that the body of tinfoil is suliicientlythin to allow an appreciable number of rays to penetrate so as toclearly bring out the flesh line of the hand and the bone lines of thehand. Even if the label were placed on top of a fracture the same couldbe readily seen through the label.

By providing a thin flexible label adapted to be secured to the objectby glue or other adhesive a proper and comprehensive label may beproduced on any object, as for instance the hand, head or any part ofthe body, without danger of injuring the negative and without in any Wayinconveniencing the patient. After the label has been affixed to thehand or other object the object is placed upon the negative and theX-rays are caused to penetrate the hand or object and strike thenegative in the usual manner for producing a radiograph. After theexposure has been made for the usual length of time the plate isdeveloped in the usual .manner, as the label. really forms part of theradiograph though acting only as a label.

\Vhat I claim is i 1. A radiograph label comprising a thin sheet ofmetal partially opaque to X-rays, a legend on said sheet, said legendbeing arranged so that the permeability thereof will be different fromthe thickness of the sheet whereby a difierent number of rays areallowed to penetrate at that point.

2. A radiograph label comprising a tinfoil sheet sulficiently thin toallow most of the rays of an X-ray machine to penetrate the same, saidsheet being formed with a legend thereon, said legendbeing arranged insuch a manner that the same will be of a difi'erent permeabilityto theremaining part of the sheet whereby a different number of rays areallowed to penetrate at that point.

3. A radiograph label comprising a tinfoil sheet sufficiently thin toallow most of the rays of an X-ray machine to penetrate the same, saidsheet being of such a consistency as to be capable of having a legendproduced thereon by writing, said writing being done in such a manner asto cause the sheet to have a difi erent opaqueness at the point ofwriting to the remaining part of the sheet so as to allow a differentnumber of rays of an X-ray machine to penetrate at that point. 7

4. A radiograph label, comprising a sheet of lead sufiiciently thin toallow most of the rays of an X-ray machine to penetrate the same, saidsheet being formed With a legend thereon, the sheet at the point wherethe legend is provided being thinner than the remaining part of thesheet, whereby a greater number of rays are allowed to penetrate at thatpoint.

5. A radiograph label, comprising a sheet partially opaque to X-rays, alegend on said sheet said legend being arranged so that the permeabilitythereof will be-different from the remaining part of the sheet, wherebya different number of rays are allowed to penetrate at that point.

6. A radiograph label, comprising a pliable sheet partially opaque toX-rays, said sheet being formed with a legend adapted to permit adifferent number of rays to pass at that point.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
